How communicative trust shapes cognitive trust

This paper introduces the concept of communicative trust, defined as trust in a speaker's cooperative linguistic behavior. Communicative trust is distinguished from both cognitive trust and rapport. The distinction between communicative and cognitive trust is elucidated through Grice's maxims of communication. Although communicative trust is neither necessary nor sufficient for cognitive trust, it can nonetheless promote or generate cognitive trust. The paper also addresses the more specifically epistemological question, whether and to what extent the transition from communicative to cognitive trust can be rational or reliable.
